Calling a program

Dear List - Can you not call a PHP script from a form -- action = 'program.php'? In my hands it does not work... I have tried the following include program.php; later in the program ... form . . echo "<input type='hidden' name='next_step' value='step14' />"; . . . . switch ( $_POST['next_step'] ) { case 'step14': { P7a.php(); } } } //end Switch The result of this is that program.php runs at the start of the script, and step14 is never called. I am totally confused. If you need more details, please specify. TIA. Ethan
